WindStax has also pioneered linkages to microgrids and batteries to store energy. Their ZeroFirst™ technology system allows customers to transition between alternative energy sources, smooth supply and demand cycles, and still have public power as a fallback.

WindStax turbines are non-directional and need little wind to start operating. They can work in wind speeds as low as five miles per hour, and are portable, making them perfect for city use. They are also avian-friendly and silent.
